Problems solved by technology

However, the coating materials currently used for coated slow-release fertilizers are usually non-fertilizer polymers, which have low effective fertilizer content, high product costs, and high prices of non-fertilizer polymers, which eventually lead to low yield and sugar content of sugarcane, and at the same time cause Ecological environment pollution in sugarcane area

Embodiment 1

[0040] The sugarcane slow-release fertilizer production process provided by the invention is produced by a fertilizer enterprise according to the process.

[0041] Prepare 60kg of 40% sulfuric acid solution and 60kg of 40% phosphoric acid solution, prepare them in the spare tank, pass 389 kg of calcium magnesium phosphate fertilizer, 61 kg of monoammonium phosphate, 83 kg of potassium chloride and 44 kg of filling materials through the Raymond mill respectively Grind to 100 mesh for later use; put 423 kg of urea into the disc granulator, start the granulator, spray 40% dilute sulfuric acid solution, and put the ground potassium fertilizer into the disc granulator. It will quickly absorb and wrap on the surface of urea particles, spray 40% phosphoric acid solution, add finely ground phosphate fertilizer and filler for granulation after the granules are wet, and observe the granulation of the granulation disc during this process. For the bonded powdery raw materials, 40% dilute ...

Embodiment 2

[0043] The sugarcane slow-release fertilizer production process provided by the invention can be produced by fertilizer enterprises according to a certain formula.

[0044]Prepare 40kg of 30% sulfuric acid solution and 40kg of 30% phosphoric acid solution respectively, prepare them in the spare tank, and grind 306kg of calcium magnesium phosphate fertilizer, 92kg of monoammonium phosphate, 167kg of potassium chloride and 8kg of filler to 80 Put 417 kg of urea into the disc granulator, start the granulator, spray 30% dilute sulfuric acid solution, put the ground potassium fertilizer into the disc granulator, at this time the potassium fertilizer will be quickly absorbed and Wrap it on the surface of urea granules, spray 30% phosphoric acid solution, add phosphate fertilizer, amino acid and filler to granulate after the granules are wet, observe the granulation condition of the granulation disc during this process, if there is still unbonded powder For raw materials, 30% dilute ...

Embodiment 3

[0046] The sugarcane slow-release fertilizer production process provided by the invention can be produced by fertilizer enterprises according to a certain formula.

[0047] Prepare 50kg of 35% sulfuric acid solution and 40kg of 35% phosphoric acid solution respectively, and prepare them in the spare tank. Grind 500kg of ordinary calcium superphosphate, 140 kg of potassium sulfate and 44 kg of filling material to 50 mesh respectively by Raymond mill, and set aside ; Put 326 kg urea into the disc granulator, start the granulator, spray 35% dilute sulfuric acid solution, put the ground potassium fertilizer into the disc granulator, at this time the potassium fertilizer will be quickly absorbed and wrapped in the On the surface of urea granules, spray 35% phosphoric acid solution to make the granules wet, then add phosphate fertilizer and filler to granulate. During this process, the granulation of the granulation tray can be observed. Add 35% dilute phosphoric acid solution so th...

Abstract

The invention relates to a production process of a sugarcane slow release fertilizer, belonging to the technical field of fertilizers. The production process adopts a fertilizer wrapping fertilizer process to prepare a wrapped fertilizer type efficient slow release fertilizer for sugarcane, the combination of three main nutrient fertilizers of nitrogen, phosphorus and potassium is realized, and a three-element compound fertilizer is formed; according to the nutritional requirement of the growth of sugarcane, nitrogen fertilizer urea serves as a core layer, a potassium fertilizer serves as a middle layer, and a phosphorus fertilizer serves as an outer layer; and when the sugarcane slow release fertilizer serves as a base fertilizer and is applied to soil together with sugarcane seeds, the sugarcane slow release fertilizer can meet the nutritional requirement of the sugarcane for the whole life, firstly, at the growth prophase, the phosphorus fertilizer and the potassium fertilizer are released to promote the root growth and tiller of the sugarcane, and at the growth metaphase of the sugarcane, the nitrogen fertilizer of the core layer is released to promote the great growth of the sugarcane. The sugarcane slow release fertilizer is applied once when the sugarcane is planted, and the whole growing season does not need fertilization, so that the problems that the sugarcane is fertilized for many times, a lot of manpower and financial resources are consumed, and the sugarcane is low in yield and sugar content at present can be effectively solved.

Description

Technical field: [0001] The invention belongs to the technical field of fertilizers, in particular to a production process for sugarcane slow-release fertilizers. Background technique [0002] In the main sugarcane producing areas in my country, multiple fertilizations are required to meet the nutrients required for sugarcane production. Generally, the entire production period of sugarcane requires the application of basal fertilizer, seedling fertilizer, evil fertilizer, stem fertilizer and tail fertilizer. Repeated fertilization is labor-intensive, time-consuming and labor-intensive, and is no longer suitable for the development of the modern sugarcane industry. At present, slow-release fertilizer has become the direction of sustainable development of the fertilizer industry in various countries in the world. There are two kinds of slow-release fertilizers: organic synthetic slow-release fertilizer and coated slow-release fertilizer. Among them, the coated slow-release fe...
